A B S T R A C TTitanium alloys are one of the materials extensively used in the aerospace industry due to its excellent properties of high specific strength and corrosion resistance. On the other hand, they also present problems wherein titanium alloys are extremely difficult materials to machine. In addition, the cost associated with titanium machining is also high due to lower cutting velocities and shorter tool life. The main objective of this work is a comparison of different cooling techniques during cryogenic machining of titanium alloys. The analysis revealed that applied cooling technique has a significant influence on cutting force and surface roughness (Ra parameter) values. Furthermore, in all cases observed a positive influence of cryogenic machining on selected aspects after turning and milling of titanium alloys. This work can be also the starting point to the further research, related to the analysis of cutting forces and surface roughness during cryogenic machining of titanium alloys.

“…Wang and Rajurkar (2000) experimentally validated that the surface finish of the machined titanium and Inconel ® alloy parts with cryogenic cooling was much superior than that of conventional machining. In addition, Venugopal et al (2003) developed two liquid nitrogen jets in one system for cooling the rake surface and principal flank, tool nose and auxiliary flank, respectively.…”

Today, hybrid manufacturing technology has drawn significant interests from both academia and industry due to the capability to make products in a more efficient and productive way. Although there is no specific consensus on the definition of the term 'hybrid processes', researchers have explored a number of approaches to combine different manufacturing processes with the similar objectives of improving surface integrity, increasing material removal rate, reducing tool wear, reducing production time and extending application areas. Thus, hybrid processes open up new opportunities and applications for manufacturing various components which are not able to be produced economically by processes on their own. This review paper starts with the classification of current manufacturing processes based on processes being defined as additive, subtractive, transformative, joining and dividing. Definitions of hybrid processes from other researchers in the literature are then introduced. The major part of this paper reviews existing hybrid processes reported over the past two decades. Finally, this paper attempts to propose possible definitions of hybrid processes along with the authors' classification, followed by discussion of their developments, limitations and future research needs.

Plastic parts such as syringe, phone cases, containers, etc. are formed in the mold under the molten temperature and with the high pressure. Plastic sticking to the mold surface during forming process is a serious practical problem for the manufacturing. The sticking limits mold lifetime, reduces production speed and degrades product surface quality. Mold material, surface condition, plastic chemical properties and molding parameters effect on the sticking. In this work, the effectiveness of surface treatments including mechanical polishing, plasma nitriding, hard DLC coating and TiB 2 ion implantation were investigated in regards to reducing the plastic sticking on the steels -SKD61, HPM38 and PX5 surface. The surface finishing was characterized with surface roughness, hardness, friction coefficients and wettability. Adhesion strength of the steel -plastic interface for the plastic materials: polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), poly-butylene terephthalate (PBT) were measured with the developed method, with the concept of real surface area. It was shown that, for the different plastics, the appropriate die material and die finishing must be chosen to provide the lowest plastic sticking.
